ABSTRACT:
A flat clip or staple is manufactured from a continuous strip of flat sheet material in coil form by first stamping out intermediate portions of material between each of the blanks to be formed into a discrete staple while retaining the blanks in the continuous strip. The strip is then subjected to a second stamping process where each discrete staple is severed from the strip, formed into the required shape and the excess waste material removed from the continuous strip. The second stamping process is located immediately adjacent the final stapling assembly operation, such that the staples never need to be transported to the final stapling operation site in separated form.
